The Work Personality Index is a psychometric assessment that measures personality traits. It was designed by Dr. Donald Macnab and Shawn Bakker of Psychometrics Canada . The questionnaire is designed to identify personality traits that relate to work performance; it takes most people 10 minutes to complete.
The community validation sample consisted of 520 adult residents of the Eugene-Springfield, Oregon area. The members of this sample were more heterogeneous from the other samples, in terms of gender, education, ethnicity, and age. They too completed CPI under the same circumstances as the other two sample groups. [9] [10]
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
They are then asked if, in their opinion, the management behaviour they have seen is good or bad practice. The scenarios are very effective in getting managers to be a part of the assessment process because they are based on the real situations that they regularly have to deal with on a day-to-day basis, resulting in high face validity scores.
In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure. [ 1 ] [ 2 ] For example, the validity of a cognitive test for job performance is the correlation between test scores and, for example, supervisor performance ratings.
The negative predictive value for the total sample was 0.93 making it a good tool to rule out cognitive impairment. On all measures the GPCOG performed at least as well as the mini–mental state examination (MMSE). [1] [2] Of note, positive and negative predictive values depend on the prevalence of the disorder in the studied population.
The Miller Analogies Test (MAT) was a standardized test used both for graduate school admissions in the United States and entrance to high I.Q. societies.Created and published by Harcourt Assessment (now a division of Pearson Education), the MAT consisted of 120 questions in 60 minutes (an earlier iteration was 100 questions in 50 minutes).
Researchers C. W. Allinson and J. Hayes, in their own 1996 publication of a competing cognitive style indicator called Cognitive Style Index [13] in the peer reviewed Journal of Management Studies, noted that "there appears to be little or no published independent evaluation of several self-report measures developed as management training tools ...
